SSHv2 provides stronger encryption than SSHv1, requiresSUN JRE 1.4 or above and can only connect to servers that support SSHv2. Terminal Servicesrequires either Java or ActiveX on the client machine.

As examples of tasks you can perform and environments you can reach through Virtual Off ice,you can connect to:

Intranet Web or HTTPS sites If your organization supports Web-based email, such asOutlook Web Access, you can also access Web-based email

The entire network by launching the NetExtender client

FTP servers for uploading and downloading files

The corporate network neighborhood for file sharing

Telnet and SSH servers

Desktops and desktop applications using Terminal Services or VNC.

Email servers via the NetExtender client.

The administrator determines what resources are available to users from the SonicWALL SSLVPN Virtual Office. The administrator can create user, group, and global policies that disable

access to certain machines or applications on the corporate network.The administrator may also define bookmarks, or preconfigured links, to Web sites orcomputers on the intranet. Additional bookmarks may be defined by the end user.

SonicWALL NetExtender is a software application that enables remote users to securelyconnect to the remote network. With NetExtender, remote users can virtually join the remotenetwork. Users can mount network drives, upload and download files, and access resources inthe same way as if they were on the local network.

Certificates

If the SSL-VPN appliance uses a self-signed SSL certificate for HTTPS authentication, then it

Verifying User One-Time Password Configuration

If you are successfully logged in to Virtual Office, you have correctly used the One-TimePassword feature.

If you cannot login using the One-Time Password feature, verify the following:

Are you able to login to the Virtual Office without being prompted to check your email for a

one-time password? You have not been enabled to use the One-Time Password feature.Contact your SSL VPN administrator.

Is your email address correct? If your email address has been entered incorrectly, contactyour SSL VPN administrator to correct it.

Is there no email with a one-time password? Wait a few minutes and refresh your emailinbox. Check your spam filter. If there is no email after several minutes, try to login againto generate a new one-time password.

Have you accurately typed the one-time password in the correct field? Re-type or copy andpaste the one-time password.

Troubleshooting Common Errors

Symptom I see an error message indicating that an email configuration is invalid, and I haveverified that the One-Time Password feature is configured correctly.

Possible Cause The SonicWALL SSL VPN One-Time Password feature does not supportemail servers that require passwords or other authentication. Your email server must allowanonymous access to allow the One-Time Password feature to successfully send a one-timepassword.
